Invention Explanation (1) [Technical field to which the invention belongs] The present invention relates to a heat pump air conditioner using a non-azeotropic mixed refrigerant [Known Technology] The conventional heat pump air conditioner uses pipes to exchange heat between a compressor and an air side. The refrigerant, water-side heat exchanger, expansion valve, and four-way valve are connected together to form this refrigeration cycle. By switching the four-way valve, the refrigerant in the air-side heat exchanger, expansion valve, and water-side heat exchanger is connected. The flow sequence is reversed for air-conditioning operation or heating operation. In this refrigeration cycle, when the cooling operation and the heating operation are switched, the directions of the refrigerant flowing in the air-side heat exchanger are reversed. Here, the air flow that becomes the cooled or heated fluid always passes through the heat exchanger in the same direction. Therefore, when the air-conditioning operation or the heating operation is performed, the refrigerant flows in the same direction as the air, and becomes a parallel flow. [Problems to be Solved by the Invention] For such a heat pump type air conditioner, if a non-azeotropic mixed refrigerant is used as the refrigerant, the refrigerant has a gas-liquid mixing region (two-phase region) in the condensation process of the refrigeration cycle. At the same condensation pressure, the condensation temperature on the saturated vapor line is the highest, and the condensation temperature on the saturated liquid line is the lowest, so there will be a temperature gradient; therefore, when the refrigerant flows in the air-side heat exchanger When the direction and the air flow are parallel, the heat transfer performance of the heat exchanger of non-azeotropic mixed refrigerant is lower than that of pure refrigerant or azeotropic refrigerant, which will cause the cooling and heating capacity of heat pump air conditioners to be significant.囡 National Standard (CNS) Λ4 specification (210X297 »苁; _4. --------- installation —„ ----- order ------ Quan (please read the precautions in the back first) (Fill in this page) [Institute for Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs -5- 416000 λ Η " V. Description of the invention (2) to reduce the problem "Therefore, when using non-azeotropic mixed refrigerants, in order to ensure that The performance of pure refrigerant or azeotropic refrigerant is the same. In the cooling operation and heating operation, the temperature gradient characteristics of non-azeotropic mixed refrigerant must be considered to make the refrigerant and air convect. About this type of heat pump air conditioner, such as Japanese special It is described in Kaiping 9 — 1 9 6 4 8 9. This heat pump air conditioner is connected to a compressor, an air-side heat exchanger, a water-side heat exchanger, a pressure reducing mechanism, and a four-way valve through piping. Together, this refrigeration cycle is formed; by switching the four-way valve, the direction of refrigerant flow in the air-side heat exchanger, whether in cold air operation or heating operation, flows in opposition to the air flow. However, This heat pump type air conditioner uses two air-conditioning capillary tubes and one heating capillary tube as decompression mechanisms, and uses a backflow prevention valve, which has a complicated and expensive structure. In addition, an outdoor heat exchanger is used for air For heat exchange rather than heat exchange with water, the problem of using a non-azeotropic mixed refrigerant in the water-side heat exchanger is not fully considered. The present invention is to solve the above problem. The problem was invented, and the object is to provide a heat pump air conditioner that uses a non-azeotropic mixed refrigerant with different boiling points as a refrigerant, which is a mixture of at least two kinds of substances. When heating and heating operation, appropriate cooling performance and heating performance can be obtained respectively. [Means for solving the problem] The heat pump air conditioner of the present invention is directed to compressing a compressor, an air-side heat exchanger, and a water-side heat exchanger by using pipes. , Expansion valve and four-way valve connected to this paper size apply to the Chinese National Standard (CNS) Λ4 specification (210: < 297 male 1 1 I-II--III-1— taxi I- 1 II I.

Description of Invention (3) Together to form a refrigeration cycle A heat pump air conditioner that uses a non-azeotropic mixed refrigerant that is a mixture of at least two substances with different boiling points as the refrigerant flowing in the refrigeration cycle is characterized in that: The exchanger is composed of a space separated by a plurality of plates, and the refrigerant and water alternately flow for heat exchange; the refrigerant circulation ports of the water-side heat exchanger are provided at upper and lower places, and the expansion valve is based on The flow direction of the refrigerant has different valve characteristics. Moreover, by switching the four-way valve, the direction of the refrigerant flowing in the air-side heat exchanger is the same whether it is in the cooling operation or the heating operation. The air flow and the refrigerant flow are always relatively opposed to each other; and when the air-conditioning operation and the heating operation are performed, the refrigerant flow direction in the expansion valve is opposite; and in the water-side heat exchanger, when the air-conditioning operation is performed The refrigerant flows from the lower part to the upper part, and when the heating operation is performed, the refrigerant flows from the upper part to the lower part.

This refrigeration cycle is constituted by piping connecting the compressor 1, the air-side heat exchanger 2, the water-side heat exchanger 3, the expansion valve 4, and the four-way valves 5, 6, and 7 '.

Description of the Invention (4) Board 3 a overlaps laterally to form this water-side heat exchanger 3. The refrigerant flow openings 3 b and the water flow holes 3 c of the water-side heat exchanger 3 are respectively arranged side by side on the plates 3 a constituting the side of the heat exchanger. The upper and lower ends. As shown in Figure 3, the structure of the expansion valve 4 has different flow resistances for the refrigerant flow direction during air-conditioning operation and the refrigerant flow direction during heating operation, so they are suitable for cooling operation or heating. Valve characteristics of the refrigerating cycle during operation. Here, the solid lines and dotted lines of the four-way valves 5 '6, 7 indicate the states during air-conditioning operation and heating operation, respectively, and the solid-line arrows in Fig. 1 And dotted arrows indicate the refrigerant flow direction during air-conditioning operation and heating operation, respectively. During the refrigeration cycle The flowing refrigerant is a non-azeotropic mixed refrigerant mixed with at least two substances with different boiling points. When the air-conditioning operation is performed, the refrigerant 1 is compressed by the compressor 1 into a high-temperature and high-pressure refrigerant gas, and passes through the four-way valve 5, The solid-line path of 7 flows into the air-side heat exchanger 2. At this time, the refrigerant gas and the blower's blower flow in opposite directions for heat exchange, and become a high-temperature and high-pressure liquid refrigerant. This high-temperature and high-pressure liquid refrigerant passes through the four-way valve 6 The solid-line path is depressurized by flowing in the direction shown by the solid line in the expansion valve 4, and then flows into the water-side heat exchanger 3 through the refrigerant circulation port 3b at the lower end of the water-side heat exchanger 3. Then, When passing through the water-side heat exchanger 3, it exchanges heat with water to become a low-temperature and low-pressure refrigerant, and then flows out from the upper-end refrigerant circulation port 3b. In this water-side heat exchanger 3, the refrigerant flows from the lower part to the upper part, It exchanges heat with water flowing in the adjacent place, and changes from the gas-liquid two-phase state to the gas phase state. The low-temperature and low-pressure refrigerant flowing out of the water-side heat exchanger 3 passes through the solid line path of the four-way valve 5 and returns to the paper.

Description of the invention (5) into the compressor 1. During heating operation, switch the four-way valves 5, 6, and 7 to the positions shown by the dotted lines. By this means, the high-temperature and high-pressure refrigerant gas compressed by the compressor 1 flows into the water-side heat exchanger 3 through the refrigerant flow port 3 b at the upper end portion of the water-side heat exchanger 3 through the dotted path of the four-way valve 5. At this time, the refrigerant gas exchanges heat with the water passing through the water-side heat exchanger 3 to become a high-temperature and high-pressure liquid refrigerant, and then flows out from the lower-end refrigerant circulation port 3b. In this water-side heat exchanger 3, the refrigerant flows from the upper part to the lower part, and exchanges heat with water flowing in the adjacent place, and changes from a gas phase state to a gas phase state. Then, the high-temperature and high-pressure liquid refrigerant flows in the expansion valve 4 in a direction opposite to the flow direction during the cooling operation, as shown by a dotted line, and is depressurized, and then flows through the dotted path of the four-way valves 6 and 7 to the air side. Inside the heat exchanger 2. In addition, as in the case of air-conditioning operation, the refrigerant and the blower's air supply flow in opposite directions for heat exchange, and become a low-temperature and low-pressure refrigerant, and return to the compressor 1 through the dotted path of the four-way valve 6. In this embodiment, as shown by the solid arrow and the dashed arrow in FIG. 1, by switching the three four-way valves 5, 6, and 7, the flow direction of the refrigerant in the air-side heat exchanger 2 can be changed. Whether in air-conditioning operation or heating operation, they are all in the same direction. Thus, the air flow and the refrigerant flow can always be opposed to each other. By this means, the temperature difference between the refrigerant and air during heat exchange can be increased, and even when a non-azeotropic mixed refrigerant is used, it can be the same as when using pure refrigerant or azeotropic refrigerant. Air conditioning and heating performance. In addition, when it is considered to be relatively fluid, for the expansion valve 4, the cooling medium flows during the air-conditioning operation and the heating operation.

Description of the invention (6) The directions are opposite. Since the expansion valve 4 has valve characteristics suitable for the refrigeration cycle during air-conditioning operation and heating operation according to the flow direction of the refrigerant, the price is cheap and when performing air-conditioning operation and heating operation * Appropriate air-conditioning performance and heating performance can be obtained respectively. Furthermore, as the water-side heat exchanger 3, since the refrigerant and water alternately flow in a space separated by a plurality of plates 3a, heat is exchanged. The exchange performance is good and can be miniaturized. When this plate heat exchanger 3 is used, in the water-side heat exchanger 3, the refrigerant flows from the lower part to the upper part when the air-conditioning operation is performed, and the refrigerant flows from the upper part when the heating operation is performed. Down Therefore, it is possible to smoothly change from a gas-liquid two-phase state to a gas phase state during air-conditioning operation and from a gas-phase state to a liquid state during heating operation to obtain proper cooling and heating performance. [Effects of the Invention] If According to the present invention, for a heat pump air conditioner using a non-azeotropic mixed refrigerant obtained by mixing at least two substances having different boiling points as a refrigerant flowing in a refrigerating cycle, a low-cost, small-sized air conditioner can be obtained. 'When performing air-conditioning operation and heating operation', heat pump air conditioners with appropriate air-conditioning performance and heating performance can be obtained.
